No activity going on

The yard was full of birds, squirrels, bunnies, and chipmunks this morning so Mama and I spent an hour on the back porch. All of a sudden it got quiet and Mama commented that there was no activity going on. Two minutes later I spotted this Cooper's Hawk in the corner of the yard. I was only able to snap one picture before it flew away. You can see his breakfast, which he carried away, on the ground in front of him.
